tain current therefrom.

Devices of the character above referred to are generally secured adjacent the end of a trolley pole and consist of a body member ,to which is pivotally secured a carrier member preferably provided with a removable insert or shoe member.

One of the principal objects of my invention is to design and construct a device in which a portion or member thereof may be easily and quickly loosened or removed so as to detachably secure a carrier member. 1

It is also an object of my invention to provide recesses for the means employed in securing the arm members or portions together so that the means do not extend or project beyond the confines of the body member or support.

A further object of my invention is to provide a device in which the insert or shoe member carried by the carrier member is located in close proximity to the pivotal axis of the means employed in connecting the carrier to the support, the advantage of which insures more efficient frictional contact between the insert and trolley WlI'E.

Another object is to design and construct the carrier member with integral transverse projecting portions which provide a pivotal connection between the carrier and the support.

A still further object of my invention is' to design and construct a device which is very substantial and durable.

Many other objects and advantages of my invention will appear after considering the following description in connection with the drawing annexed hereto.

With reference to the drawing wherein the parts of the device are designated by numerals, Fig. 1 is a side view of the current collecting device showing the general arrangement of its several elements or parts;

Fig. 2 is a section taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a section taken substantially on line 33 of Fig. 1; and

Fig. 4 is a section taken through a portion of the carrier member. I 7 Considering the several figures disclosed in the drawing, it will be evident that the body member is generally designated 1 and is preferably de-- signed to be secured adjacent the end of a trolley pole. The member which is designed to receive the removable insert or shoe member is generally designated 2 and as shown is pivotally secured with respect to the body member generally designated 1. As shown in Fig. 2 the body member 1 is provided with an integral arm portion 3, and a side portion or member 4 is adapted to be detachably connected or associated with respect to the body member and integral side portion 3. The end such as 3 of the removable side portion is preferably rounded and seated in a recess such as 1, so that the exposed face of the side portion is flush with the side of the wall of the body. The

integral arm portion 3, is provided with an inte- I gral projection or circular boss portion 5, the extreme end being adapted to extend into the recess or aperture 7 and abut wall '7' provided in the integral projection or bossportion 8 formed on the removable side member 4; whicharrangement will provide means for gauging the space between the arm portions. A hole or aperture 9 is provided in the boss portion 5 of the integral side portion 3 and an aperture of the same diameter is-provided in the boss portion 8 of the removable side member 4.' A bolt such as 11 provides means for cooperatively securing the said side portions or arm members together. As above stated, one of the important objects of myinvention is to arrange the locking means or in other words, the bolts, in a position so that they do not extend beyond the confines of the arms and this is accomplished by providing recesses 12 and 13 in the arms, which respectively receive the head and nut of the bolt 11. I or arm 4 is also secured to the body portion of the support; and as clearly shown in Fig. 3, is provided with an inwardly extending boss portion 14 which is located in a recess 14 provided in the body 1, and a bolt such as 15 is adapted to extend through the aperture 16 provided in the body portion and through a hole or aperture 17 provided in the boss portion 14. The .body member is provided with a recess 18' and the side member 4 is provided with a recess 19 so as to respectively receive the head and nut which form a part of the bolt 15 and the arrangement is therefore similar to that mentioned concerning bolt 11.

It will be evident from the description thus far, that the support for the carrier member generally designated 2 consists of a body portion 1 formed with an integral extending arm portion and that a removable side portion or member is adapted to be detachably associated or connected with the body portion and integral side portion of the sup port, and that improved or novel means are em- The removable side member transverse groove such as 34 which is designed ployed for cooperatively securing the several parts together in a rigid and substantial manner.

The integral arm or side portion 3 of the body member and the removable side member 4, as shown, are designed to provide bearings such as 20 which are provided with apertures 21 through which means extend for pivotally connecting the carrier generally designated" 2 with the support or body portion of the device. The body portion 22 of the carrier is elongated and provided with integral projections such as 23 which extend transversely of the carrier and ride in the apertures 21* of the bearings 20. It will be noted that the width of the body portion 22 of the carrier is substantially equal to the width of the bifurcation formed by the bearings 20, and therefore, there is substantially no side play or lateral movement of" the carrier with respect to the. support. It :might be mentioned that the integral portions 23 which provide a pivotal connection between the carrier and support makes a more rigid and substantial construction. An undercut longitudinal groove is formed in the body portion 22'of the carrier and thebottom' thereof is designated 24 and the walls thereof, 25. Any insert or shoe member such as 26 conforming to the shape of the undercut groove is adapted to be removably mounted within said groove so as to engage the bottom and side walls thereof, and as clearly shown, and as above referred to, the insert is located in close proximity to the pivotal axis of the means providing the connection between the carrier and'support. In other words it is an object'of my invention to design and; construct a device in which the axis of the pivotal connection is located in close proximity to the face of the insert member which is'adapted to slidably engage the trolley wire, the effect of which efliciently insures a better frictional engagement or contact with the trolley wire; or in other words, there are more points of contact between the insert or shoe member and the trolley wire than there would otherwise be if the axis of-the pivotal connection'was at a point some distance from the face. of theinsert member.

Thecarrier' member generally designated 2 is formed; with upstanding side walls which are designed with concave cheek portions 28;andthe removable insertmember is formed to provide a longitudinal concavegroove 27, which more or less conforms to the, curvature of the cheek portions 28, all of which provides a longitudinal concavity which receivesthe trolley wire. As clearly shown in Fig. 2 the body portion22 of the carrier isprovidedwith a longitudinal'slit or kerf 29 which obviously permits the side wall portions of the carrier to be drawn together or to be adjusted with respect to each other in a manner whereby the insert 26 may be adjusted with respect to the carrier." Each end ofthe insert 26 is preferably rounded as at 30 and eachend of the carrier may be rounded'as at 31;

The means employed for locking the insert member 26 in the undercut'groove in the carrier, in the present instance, consists of a pair of-bolts 32 which'extend throughholes or apertures such as 33 which extend transversely throughthe body portion 22 of the carrier, the centerofeach aper= ture being located at a point-below the base 24 of theundercut groove. Formed along the bottom of the insert member adjacent each end is' a to receive a portion of a bolt 32.

' "Oneimportant-feature embodied in the construction and-not-set forth hereinbefore, is the provision of a portion or-member'such as 38 at In view of the foregoing description it will be evident that I have designed and constructed a current collecting device which consists of a body member or support and a carrier member, and that the support consists of two parts or members which are adapted to be cooperatively secured or adjusted with respect to each other in a' manne rto receive and support a carrier member. It will also be evident that the pivotal axis of themeans-providing the pivotal connection between the carrier member and the support is located" at a point in close proximity to the face of the insert or shoe member, the result of which insures amore efficient contact or frictional engagement between theinsert and trolley wire. .In otherwords, the removable insert or shoe member is located in close proximity to the pivotal axis of the means employed in connecting the carrier with the support.

Having thus described my invention it is obvious that various immateriallmodifications may be made in the same withoutdeparting from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
